New Immunotherapy Treatment Shows Good Results Against Breast Cancer
The treatment would help the immune system recognize HER2 protein in breast cancer cells. Their approach involves the creation of the immune cell vaccine, called dendritic cells that are harvested from each individual patient and then used to create a personalized vaccine for each patient. P>
The researchers conducted clinical trials in 54 women with cancer of early HER2-expressing breast cancer to determine the efficacy of the treatment. To prepare the vaccine, the dendritic immune cells were separated from the blood of each of the women and injected into the patients once a week for six weeks in a lymph node, tumor or both.
The results showed that treatment was able to stimulate an immune response in most patients. Approximately 80% of the patients evaluated had a positive immune response and the vaccine was considered to be well tolerated and with low toxicity. However, there were adverse events such as fatigue, injection site reactions and chills.
In 13 patients immunotherapy through the vaccine had a complete response, ie the cancer was no longer identified in samples taken by surgical procedures. In addition, the greatest efficacy was in women with ductal carcinoma, one of the most common types of cancer.
The aim of the study is to help patients with early breast cancer by restimulating the immune system to recognize and target the HER2 protein yet during the development of cancer.
Furthermore, it is not yet known whether immunotherapy would be used to cure cancer definitively or just treat it. The drugs are recent, the patients they use have yet to be seen, so that they can eventually find out if the tumors return or not.
In these times when the infection caused by the Zika virus scares Brazilian society, especially those couples who intend to become pregnant, the PCR test is the technique of detecting the virus due to the accuracy of the result (99.99% accuracy) and especially because of the speed with which we can obtain the result.
The pharmacy pregnancy test detects the presence or absence of the hormone beta-HCG in the urine. This hormone is produced from the time the egg is implanted - that is, as soon as the gestation begins. Thus, a positive pregnancy test is one that identifies the presence of beta-HCG in the urine. There are several types of pregnancy tests.
